To all iolwm t may concern.' -A j Be it known thatl I, IsAAc A.' BAUM," a

. citizen of the United States, 'and resident of Memphis, in the county of Shelby and State" of Tennessee, have inventedfcertam new and Vuseful Improvements 1n Frame Construc-VV tions, of which the following is a specilication. Y Y p V i This invention relates toV improvements in building constructions, relating particularly to the constructionof frames for various openings, such as windows, doors, etc., and

itconsists of the constructions, combinations and arrangements herein described and claimed.y y I An object lof the invention isto provide a metallic channel for both the interior andy exterior of "a" wall' opening, severaluof the A' important advantages derived from thev use of the channelbeing that iteliminatescas-v ings and wood trim around the opening'and provides a guide orv gauge up to which a plastic covering can be iinished.

Other objects and advantages appear in the following specification, reference being had to the accompanying drawing, in

which- Figure 1 is an elevation of a conventional window illustrating the simplicity obtained by the use of the improved frame construction.

Figure 2 is a sectional perspective view of a portion of the wall at the window opening illustrating the corelation and combina- Figure 3'is a detail perspective view of n a portion of the interior channel.

Figure 4 is a detail perspective view of a portion of the exterior channel.

The invention comprises a Vchannel 1, preferably made of metal, which consists of a iiange 2, web 3 and rib 4. The rib tis bent upon itself or returned at 5 providing a reinforcementfor the rib and also a substantial edge up to which th-e plastic wall coating may be carried.

These foregoing elements are bent substantially as shown in Figures 3 and 4. The flange 2 is substantially at right angles to the web 3, and the vrib 4 substantially at right angles tothe web 3. The flange 2 is considerably wider than the rib thereby providing ample space for nailing, as at 6 (Fig. 2). The web 3 has a crimp v7 running lengthwise thereof adjacent to the rib 4. The crimpA may be either concave as in Figure 4l or convex as in Figure-'3. lIn I either instance it is intended toprovide a weather'drip, and in addition tothatfserves to reinforce theweb'.

Figure 2'illustratesthe application loftheI metallic channel, there beingone alongboth f the interior 'and exterior ledges of anopening in the wall.v A window'v opening is selected for illustration. Thel jamb '8 provides the abutmentfor inside and outside blindl stops 9 and 10.v The extremities of i these stops opposi'tetd the jamb Shave conf-i tact with a "stud 11. A secondlstud'12is in' staggered vrelationship yto fthe. 'stud 11' thereby Vproviding a recess 13 vvinto which the lsheathing 14 can be fitted' (Fig, 2)`

bringing the inner edgefof the stud flush with the inner surface fof the stopfgand Y providing for: uninterrupted application of the plaster coat'yli'. :gf '"1v A. stuccol'coat 161is applied `to the outside, appropriate metal laths being employed in the instance ofl bothkplastic coats." The dimension between the flange 2 and rib 4 of the-` channel 1 determines the thickness of the plastic coat. In both cases thevv plastic material is Ysmoothed ofi level with the ribl 4 in this resepect forming a perfect flashing, thereby providing a simple and sanitary joint between thev wall surface and frame structure. The corner 17' is preferably nicely rounded.

Combined withboth metallic channels 1 v vare stop 'and molding strips 18 and 19.

- T hese are nailed to the adjacent stationary' frame structure and are intended to aid in vrigidifying the webs 3 of thechannels.y In

addition to performing this functionv the molding 19 seals any opening between the web 3 andthe blind stop 10. Similarly the stop 18 seals any opening between the web 3 and the blind stop 9. The space'y inside,

of the jamb 8, blind stops 9-and 10 and. stud 11 is intended to be occupied by the window weights. y 'y I Upon reference toFigure 1 a number of advantages by the use of the'invention can be seen. The channel 1 is shown extending completely around the opening. The inside, of the opening would appear the same. `The need for various kinds of casings and'window trims is entirely eliminated. 'Ihe rib 4 of the channel provides a sharp, simple, posi- Itive and beautifulinish around the opening both inside and outside vof the wall. `The plaster grounds, usually employed, are also 1eroA est...

eliminated because f the channels `form grounds Within themselves. Obviously the exposed metallic edges ofthe channels afford protection to the edges of the Wall coatings,

and by providing the ,crimpA 7 (either con-` cave or convex) moisture is stopped from creeping inwardly because it Will be com-y pelled to drip at these places.

Another advantage, namely sanitation, is also of importance. The jagged breaks usuallyjfound Where a Wall surfacermeets an opening areV entirely avoided. The Wall surface is broughtup directly to the edge ot the openingnotonly preventing a lodging place for d'rt and. a breeding placefor vermin but also preventing the passage through the air. lThe latter purpose, i. e. in Which breaks in the Wall surface are avoided, is furthered to the corresponding edgeot the stud l2 so that the edges" of 'the stud l'Z'vand stop l9 are substantiallylusln lit becomes possible to carry the plaster coat l5 all the Way over to the Window opening Without applying an excessive amount of material and Without allowing theformation of any breaks.

lVhile the construction and arrangement of the improved frame construction is that of a generally preferred form, obviously` modiications andA changes may be made lWithout departing from the spirit of the invention or the scope of the claims.

I claim e l. A plaster terminal comprising a metallic channel having a web, a relatively Wide fiange bent substantially' at right'anglesvat, one edge of the Web, arib bent substan-` tiallyk at right angles along the other edge of the web, the flange'and rib servingito gauge the thickness of a plastic Wall coat, a return upon theV rib reinforcing the rib and providing an ample termination and protection to the edge of said coat, anda crimp l formed along the web adjacentA to the rib providing a Weather drip When'the channel is incorporated in a vWall opening.

2. A plaster terminal comprising a metallic channel having a xveb, and a corrugation runningalongv the Web defining a depression to provide a'iveather drip. Y
